Reverse osmosis (RO) is a water treatment system that eliminates most dissolved elements and chemicals, such as sulfate, from water by pushing the water through a plastic surface similar to cellophane known as a "semipermeable membrane." Generally, it can eliminate between 93 and 99 % of the sulfate in drinking water. This depends on the type of unit. A small RO unit will produce about 12 liters of water per day. A little larger units, normally installed under the sink, will produce 19 to 75.6 liters of water per day. RO units generally produce only 3.8 liters of water for every 15 to 38 liters of water treated. The remaining water is rejected.Pregnant Human Data. Magnesium sulfate is administered parenterally in various clinical situations, particularly as a preventative measure for eclampsia during pregnancy. Although deemed to be safe and effective, Ricci and coworkers (1990) observed that serum sulfate concentration increased approximately twofold in 11 pregnant women treated with magnesium sulfate.Pregnant Animal Data.

. Some well water in rural areas of the United States has been known to contain upwards of 500 mg/L (Moore, 1952), and some of the “mineral” waters sold with health claims have been reported to exceed this level (Allen et al., 1989).

Florin T, Neale G, Gibson GR, Christl SU, Cummings JH. 1991. Metabolism of dietary sulphate: Absorption and excretion in humans. Gut 32:766–773.Growth responses in chicks and rats occur when sulfate is added to low-sulfate diets that are deficient in cysteine (Byington et al., 1972; Sasse and Baker, 1974b); nitrogen retention is improved in humans placed under a similar dietary regimen (Zezulka and Calloway, 1976). Whether sulfate incorporation into 3′-phosphoadenosine-5′-phosphosulfate (PAPS), or whether PAPS synthase activity could be used as a measure of sulfate adequacy, is not known. The one human study conducted to date did not attempt to measure these parameters (Zezulka and Calloway, 1976). Because sulfate is an obligatory end product of sulfur amino acid turnover, inadequate sulfate consumption (or production) is unlikely to occur in any setting other than where protein deficiency is also present.Inorganic sulfate (SO42−) is required for the synthesis of 3′-phosphoadenosine-5′-phosphosulfate (PAPS). PAPS is required for synthesis of many important sulfur-containing compounds, such as chondroitin sulfate and cerebroside sulfate. While significant levels of sulfate are found in foods and various sources of drinking water, the major source of inorganic sulfate for humans is from biodegradation due to body protein turnover of the sulfur amino acids methionine and cysteine. Dietary sulfate in food and water, together with sulfate derived from methionine and cysteine found in dietary protein and the cysteine component of glutathione, provides sulfate for use in PAPS biosynthesis. Sulfate requirements are thus met when intakes include recommended levels of sulfur amino acids. For this reason, neither an Estimated Average Requirement (and thus a Recommended Dietary Allowance) nor an Adequate Intake for sulfate is established.Pitcher MCL, Cummings JH. 1996.

Sodium sulfate supplementation has been demonstrated to inhibit methaneogenesis and stimulate the growth of sulfate-reducing bacteria in the colon of humans (Christl et al., 1992). Experimentally, colitis has been produced in Guinea pigs and rabbits that were given degraded carrageenan, sodium lignosulfate, or sulfated amylopectin in their drinking water (Marcus and Watt, 1969, 1974). It was also produced in rats, mice, and hamsters by administration of dextran sulfate sodium (Carrier et al., 2002; Ohkusa, 1985; Okayasu et al., 1990).

It is soluble in water Sulfate and undigested sulfur compounds have been implicated in the etiology of ulcerative colitis (Magee et al., 2000; Pitcher and Cummings, 1996; Roediger et al., 1997). The specific agent is thought to be hydrogen sulfide, which is produced in the colon from sulfate by sulfate-reducing bacteria. Sulfate-reducing bacteria use either sulfate or sulfite as a terminal electron acceptor, releasing sulfide into the lumen where it is converted to hydrogen sulfide gas (H2S) (Pitcher and Cummings, 1996). It is now clear that sulfate can also enter the colon from unabsorbed dietary sulfate as well as from unabsorbed sulfur amino acids, taurine, and sulfur-containing food additives (e.g., sulfur dioxide, sulfites, and carrageenan). A portion of the sulfate produced from amino-acid turnover can also reenter the gut from the circulation (Garcia and Stipanuk, 1992). Excess luminal sulfide is thought to overburden mucosal detoxification systems, resulting in impaired butyrate oxidation and colonic epithelial inflammation.
Extensive work with laboratory animals has shown that growth is stunted when dietary sulfate is purposely eliminated from both the food and water supply and when sulfur amino acids, particularly cysteine, are provided at levels resulting in deficiency signs. Importantly, the addition of sulfate to these deficient diets resulted inAdverse effects have been noted in individuals whose drinking water source contains high levels of inorganic sulfate. Osmotic diarrhea resulting from unabsorbed sulfate has been described and may be of particular concern in infants consuming fluids derived from water sources with high levels of sulfate. Some association between increased hydrogen sulfide production and risk of ulcerative colitis has been noted as well, but has not been adequately evaluated.

Clin Toxicol 25:371–382.Ion Exchange is the most known method of eliminating big quantities of sulfate from water for public, livestock, and commercial supplies, but is not generally used for individual household water treatment. It is a process where one element or chemical is replaced for another. Many people are familiar with water softening, a conventional type of ion exchange system. This system works by passing "hard" water - water with calcium and magnesium - through a tank filled with a special resin saturated with sodium ions. The minerals that cause the hardness stick to the resin, and the sodium dissolves in the water. Ion exchange systems for removal of sulfate use a different type of resin, but they work in an analogous manner. Sulfate ions in the water switch places with other ions which are on the resin, usually chloride. When the resin is full with sulfate, it must be "regenerated" with a salt solution. Water softeners do not remove sulfate, and sulfate removal systems do not remove hardness, although some commercial units contain both resins and can remove both hardness and sulfate.
The sulfate content of a few foods and beverages has been estimated (Tables 7-2 and 7-3) by Florin et al. (1993). Their analytical procedures involved acid hydrolysis; thus their sulfate values were referred to as “available” sulfate and would include not only free anionic sulfate, but also that liberated from various ester sulfates, such as amino sulfonates (e.g., heparin), nitric oxide-sulfonates (e.g., glucosinolates), phospho-sulfonates (e.g., 3′-phosphoadenosine-5′-phosphosulfate), sulfuryl-sulfonates (e.g., cysteine sulfosulfate), and oxy-sulfonates (e.g., mucin and sulfate-conjugated bile acids, but not carbo-sulfonates (e.g., taurine). Thus the methodology was designed to mimic the digestive process in- Sodium lauryl sulfate is a type of surfactant.

volving gastric acid and intestinal and bacterial enzymes that release sulfate from sulfate esters in food.A wide range of “available” sulfate values were estimated from different foods, but particularly high levels (> 1 mg/g) were found in some fruits, soya flour, certain breads, and sausages. Among beverages, several juices, beers, wines, and ciders were found to contain more than 250 mg of sulfate per L. Among inorganic sulfur sources in the food and water supply, sulfate itself, along with sulfite (SO32−), predominate, the latter being a food additive that functions as a preservative. Sulfite can also occur naturally as a consequence of fermentation (e.g., in wine). Sulfite is easily oxidized to sulfate, either in food itself or in the gut following consumption. Moreover, sulfite, as well as other inorganic sulfur compounds in the +4 valence state (e.g., SO2, HSO31−) are highly bioactive and have well-known toxic side effects (Til and Feron, 1992; Wedzicha, 1992).

If one assumes that adults whose dietary protein needs are being met will consume a daily intake of 2 g of methionine and 2 g of cysteine, an equal amount of methionine and cysteine would be oxidized, producing 960 mg of sulfur, or 2.8 g/day of inorganic sulfate. A daily intake of inorganic sulfate as high as 1.3 g/day can be obtained from water and other beverages (0.5 g/L × 2.6 L/day). A quantity of sulfate greater than this amount would likely be produced daily from metabolism of methionine and cysteine in food plus that derived from body protein turnover. An analysis of the sulfate content of various diets using foods purchased at supermarkets suggests a large variation in daily inorganic sulfate intake, ranging from 0.2 to 1.5 g (2.1–15.8 mmol)/day1 (Florin et al., 1991). Metabolism of organic sulfur compounds, such as methionine and cysteine, supplies over half of the sulfate; the remainder is supplied from preformed sulfate in water and foods (see Table 7-1)..

Sodium sulfate is a sodium salt which has the formula Na2SO4. It is known as Glauber's salt, named after the German chemist Johann Rudolf Glauber(1604-1670) who discovered it in 1625. When he discovered it, he called it sal mirabilis sodium sulfate. noun Chemistry. a white, crystalline, water-soluble solid, Na2SO4, used chiefly in the manufacture of dyes, soaps, detergents, glass Origin of sodium sulfate. First recorded in 1880-85 Sulfur dioxide (SO2) emissions represent a growing concern for industrialized countries. Sulfur dioxide in the air can react with atmospheric water to produce sulfuric acid, resulting in acid rain (Drever, 1988). This can lead to increased soil acidity and elevated levels of sulfate in ground water (Drever, 1988). Moore (1991) estimated that global SO2 emissions have more than doubled over the last 50 years.Pitcher MCL, Beatty ER, Cummings JH. 1995.

Some soils and rocks contain sulfate minerals. As groundwater moves through these, some of the sulfate is dissolved into the water. Some minerals that contain sulfate are sodium sulfate (Glauber's salt), magnesium sulfate (Epsom salt), and calcium sulfate (gypsum).Cardin CJ, Mason J. 1975. Sulphate transport by rat ileum. Effect of molybdate and other anions. Biochim Biophys Acta 394:46–54.Because the majority of body sulfate is obtained from the ingestion of protein-derived methionine and cysteine and because the primary route of sulfate excretion is in the urine, 24-hour urinary sulfate excretion is strongly correlated with 24-hour urinary excretion of urea, the end product of dietary protein metabolism (Greer et al., 1986; Houterman et al., 1997; Sabry et al., 1965). Urinary sulfate excretion has recently been suggested as a measure of sulfur amino acid metabolism in humans (Hamadeh and Hoffer, 2001; Hoffer, 2002).Sasse CE, Baker DH. 1974b. Sulfur utilization by the chick with emphasis on the effect of inorganic sulfate on the cystine-methionine interrelationship. J Nutr 104:244–251.Sulfate intake (as well as sulfate produced via amino acid turnover) typically exceeds the need for 3′-phosphoadenosine-5′-phosphosulfate biosynthesis, as evidenced by maintenance of normal levels of urinary excretion of sulfate (Cole and Evrovski, 2000) when sulfur amino acids are adequate. Recommended intakes have already been established for sulfur amino acids, which would thus cover the need for inorganic sulfate (IOM, 2002/2005). Given these two points, neither an Estimated Average Requirement (and thus a Recommended Dietary Allowance) nor an Adequate Intake for sulfate is established.

Make a 3% (w/v) Dextran Sulfate Sodium Salt solution in water and filter with a 0.45 μm cellulose acetate filter. Replace drinking water in the mouse cage with the 3% DSS solution for four days Infant Human Data. A number of studies have been conducted in human infants and very young animals because of their vulnerability to the adverse consequences of osmotic diarrhea. One study of 274 infants aged 6.5 to 30 weeks in 19 South Dakota counties involved data on frequency of diarrhea (Esteban et al., 1997). One hundred seventy households participating in the study also submitted water samples. The median sulfate level of the water samples was 264 mg/L. In approximately 83 percent of the households that submitted water samples, no significant association was found between sulfate ingestion and the reported incidence of diarrhea. The median sulfate concentration of water samples and the mean daily sulfate intake for infants who did not develop diarrhea were 258 mg/L and 29 mg/kg/day, respectively. For infants who developed diarrhea, the median water sulfate concentration was 289 mg/L, and the mean daily sulfate intake was 28 mg/kg/day. At least one small case-history study suggested that infants exposed to water sulfate concentrations above 600 mg/L may develop diarrhea (see Table 7-5) (Chien et al., 1968).
Options are. A) To remove water from the organic layer. B) To act as an acid and protonate caffeine ranging study were given six sulfate doses (in water) of 0, 400, 600, 800, 1,000, or 1,200 mg/L for six consecutive 2-day periods, while six other subjects in a single-dose study received sulfate doses (in water) of 0 and 1,200 mg/L for two consecutive 6-day periods. In the dose-ranging study, the mean sulfate intake coming from drinking water in the 1,200 mg/L group was 2.7 g, while the mean sulfate intake in drinking water in the single-dose study at 1,200 mg/L was 2.9 g due to differences in total water consumed. In both studies at the 1,200-mg/L sulfate dose, a small increase in stool mass occurred, but no complaints of diarrhea or changes in stool frequency were reported.Adult Human Data. Osmotic diarrhea and loose stools have been reported with high intakes of sulfate consumed in water (Backer, 2000). Such adverse effects are usually short term, but they may be more severe in infants. The U.S. Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC) collaborated in a 1997 study to determine whether high levels of sulfate in drinking water would cause diarrhea or other gastrointestinal disturbances in infants and in adults categorized as “transients” (i.e., those experiencing an abrupt change in water sulfate concentration from low to high) (EPA, 1999a). The study involved 105 adult volunteers from Atlanta, Georgia, including CDC and EPA employees, who were randomly assigned to one of five possible sulfate exposure groups. Sulfate concentrations (from sodium sulfate) tested in drinking water were 0, 250, 500, 800, and 1,200 mg/L. Participants were given water for 6 days. The water provided for days 1, 2, and 6 of the 6-day study contained no added sulfate, whereas the water provided for days 3, 4, and 5 contained addedThe effects of acute versus chronic sulfate ingestion on diarrhea, as well as whether and at what point adaptation occurs.Limited information is available on the extent to which 3′-phosphoadenosine-5′-phosphosulfate (PAPS) biosynthesis can be affected by available inorganic sulfate. Whether increased amounts of PAPS are needed in diseases, such as arthritis, in which sulfated compounds (e.g., sulfates of glucosamine and chondroitin) are implicated is unknown because in most studies sufficient sulfur amino acids are provided as part of dietary protein (Hoffer et al., 2001). The primary factor affecting a dietary need for sulfate is the extent to which sulfur-containing compounds are available for degradation to provide sulfate for PAPS biosynthesis. Unlike most other nutrients, the body’s need for sulfate can be met by consuming other required nutrients, sulfur amino acids. Thus a deficiency of sulfate is not found in humans consuming normal protein intakes with adequate sulfur amino acids. Ingestion of methionine, cysteine, and glutathione in foods, along with consumption of other sulfated compounds in both food and beverages, is sufficient to meet the body’s requirement for sulfate.

Anhydrous sodium sulfate (Na2SO4) is typically used in organic chemistry as a drying agent. After aqueous extractions, the organic layer always has a certain amount of water left in it Sulfur is the 14th most abundant element in the earth’s crust. Sulfate is produced in the environment from the oxidation of elemental sulfur, sulfide minerals, or organic sulfur. Soils are thought to average 850 mg of sulfate/kg and sea water 885 mg of sulfate/L (Field, 1972). Industrial sulfate results from the burning of sulfur-containing fossil fuels, household wastes (e.g., detergents), and effluents from tanneries, steel mills, sulfate-pulp mills, and textile plants. Sulfuric acid accounts for an estimated 80 percent of commercial sulfur production (NRC, 1980). Additionally, thousands of tons of sulfate compounds are produced each year; annual production of sodium sulfate was estimated at 792 tons in 1987 (EPA, 1990).where aq stands for aqueous and the + and - indicate the charge on the ion. This is the same as taking table salt (NaCl) and dissolving it in water. The solid disappears and what happens is it dissociates into Na+ and Cl- View reliable Sulfate manufacturers on Made-in-China.com.

Distillation is a water treatment system in which water is boiled, and then the steam is cooled until it condenses into a separate container. The dissolved substances, such as sulfate, remain in the boiling pot. If operated properly, distillation units can remove nearly 100% of sulfate. Distillation units need about four hours to produce 3.8 liters of water, so this type of treatment uses a substantial amount of energy in its operation. I have read that sodium sulfate is very soluble in water.
